I'm thinking this is a fine addition for 1.2.

Does anyone have any particular opinion on how they should work? I mean is
there for example occasions when they shouldn't init the underlying crypto
lib?

I would also like us to produce a more general docs for libssh2 on how it acts
and what to think about when used with threads. Like right now applications
MUST also set the crypto lib's mutex callbacks. We could consider detecting a
threads library and setting these callbacks as part of the init/cleanup
mentioned above...
